I thought that is a code violation but the contractor said it is ok to do this for treated wood. I'm not even sure that post is pressure treated. There's no perforations or stain on it like fence posts.
Could someone point me to building code related to this topic? I did a quick search with google but didn't find it.
You don't have to look up the exact web page, but a general pointer would be very helpful (e.g. search web site xxx.com for it).
If it makes any difference, I'm in the state of WA.
I need a web site with enough authority to convince the contractor. Thanks.
